What would happen if maplestory remove the damage cap from 50mil to 1bil or more?

The reason I said what I said was due to the market more or less becoming worse than it was.

I know pre-cap raise there were some items selling for 5b or something along those lines. With the cap raised to 10b I can totally see how that helped. Except..well. now that 5b item people are trying to sell for 15b.
Pre cap raise items that sold for 1b now sell for..4? 5? (as an example).

So raising the cap did not just give us a bigger wallet. Raising the cap allowed and encouraged players to charge obscenely high prices for items that would be nearly impossible to obtain through straight training/questing/bossing the game. Now the player needs to try to merch in the FM to even afford equipment worth a damn.

That level 140 quest that rewards 50-100k meso isn't worth pomegranate when your weapon from the FM costs multiple billions now. Straight up grinding and looting mesos is worth little more than potion money, whats a few mil when you need billions?

Correlation =/= Causation. Just because you saw an immediate price hike that doesn't mean it was because the game simply allowed them to be sold for more money. They were worth those prices to begin with, people just tended to avoid doing more and more transactions to prevent possible scamming. Buying equips with a 2bil meso cap was a pain in the ass, inflation has simply played its role on that even more so since then. Equips didn't just magically raise in price overnight.

I'm not arguing that getting that kind of meso is near impossible through actual gameplay, but that's a whole different problem. You're looking at the result of a problem, not the problem itself.
